To all whom it may 00ncern:'.-

Beit known that I, Join? C. citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements .in Looms, of which the following is a specification.

The present invention has to do with certain improvements in the construction of looms for weavin fabric, and the features adapted for use in connection with :looms for weaving fabrics such as grass rugs and the like, which are woven from grass twine andother comparatively large and heavy or coarse material,

In the usual type of loom the warpthreads feed continuously through the machine,

being fed from large spoolsor bundles.

These spools orbundles may be" made as large as desired so as toaccommodate as much warp material as may be necessary for thecomplete weaving operation. However, the weft thread or twine has been carried in a shuttle or the like, and consequently the amount of such material which could be carried in a continuous piece has been limited by the] size and ,capacity of the shuttle.

Where the material is large and bulky, as

is the case with grass twine and the. like,

.only a comparatively small length of the material can be putinto a shuttle of reasonable size, so that; the amount oflfabric which can be continuously woven without having to replace or replenish the shuttle is comparatively limited. This means notonly that it is necessaryto frequentlyreplace 'or replenish the shuttle, but also means that the weft thread or twine will be broken upinto comparatively short lengths. Consee quently, the fabric itself will bediscontinu-j ous as regards the weft thread and, will, eref no a estte gth d wearing q alities-Aria ne wei d h e fa a d hr ad we-.

oribody located at point outside of or away i-from the traveler itself. By this means or arrangement the amount of weft twine which can be used as a continuous unbroken piece will not in any sense be limited by; capacity of the moving or traveling part, but will be limited only by the size of the ball or mass of twine which may be conveniently"mounted at a stationary point adjacent to the loom itself.

In order to secure a fabric of special de' sign or weave, it may be desirable to use two or more weft threads or twines simultaneously. In some cases, for example, it may be desired to use a weft composed of heavy yarns or twine such as grass twine, and

also another weft of linen or cotton thread and of comparatively small size.

Another feature of my invention has t do, with the provision of a construction such that two or more wefts may-be simultaneously woven into the fabric for the purposes above mentioned. In this connection, another object is to so construct and arrange. the machine that one of said wefts maybe fed in continuously by a traveler, such as has been previously mentioned, the other weft being fed in from a shuttle of ordinary construction.

Other objects and usesof the invention will appear from a detailed description of the same, which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referringto the several drawings: Figure 1 shows a plan view of the assembled machine, the traveler being at the eXtreme right-hand limit of its movement; Fig, 2 shows a front elevation of the ma chine, being an elevation-0f. the machine looking inthesame direction in which Fig.

Referring now to the several figures, I

will describe the particular embodiment of the features of my invention illustrated therein. -In the said embodiment I have shown a rod or shaft 20 on whichthevarious warp threads or yarns 21 are carried. These threads or yarns pass over a whip roll 22 and through the upper and lower guides- 23 and 24, respectively. One set of warps passes over the guide 23 and the other set passes under the guide 24. Corresponding to thcguide 23 and the warps passing over the same, are the upper blades 25, and the lower blades 26 which correspond to the upper and lower warps which pass over and under the guides 23 and 24.

The blades 25 are mounted on a rock shaft 27 and the blades 26 are mounted on a rock shaft 28. The rock shaft 27 carries a segmental gear 29. A segmental rack 30, meshingwith the gear 29,i"s"pivoted toa stationary part at the point 31, and a crank arm 32 is connected to the segmental gear 30'. The crank arm 32 connects to the rock shaft 28..through the medium of the crank arms 33 and 34 and the connecting link 35.

By reason of; this construction the rocking of the crank 32 will cause the rock shafts 27 and 28 to rock in opposite directions,so as to cause the sets of blades 25 and '26to rock simultaneously in opposite directions.

In theirouter ends the blades 25 and 26 are provided with suitable openings for the accommodation of the warps, so that said warps will be deflected up and down by'the reciprocation of the blades. Suitable tensioning mechanisnrmay be provided for withdrawing the completed fabric 36. I do not show such mechanism, simply for the reason that-it may be of anyone or a number of familiar forms." a

In the lower portion of the machine there are pivoted'the sword arms 37 and 38. These are pivoted one ateach side of the machine, and are connected bythe top cross-piece 39. Theupper reed bars 40 depend from the cross-piece 39. Between the sword arms there is slidably mounted-another cross-piece 41, which iscarried on the upper ends of the rods 42 and 43. Said rods can-be operated within the guides or bearings 44 and 45 carried bythe sword arms 37 and 38, respectively. i The cross bar 41 carries the lower reed bars 46, which correspond to the 05 upper reed bars 40, sothat upon raising the bar 41 thelower reed bars 46 will be brought into engagement with the respective reed bars 40. The reed bars are so spaced as to accommodate the various warp threads or yarns between them during the operations of packing up the fabric.

The sword arms 37 and 38 may also be provided with a cross rod or bar 47 having openings for the accommodation of the lower reed bars 46. This cross bar 47 may be provided in its upperface with slots corresponding to the spaces or intervals between the lower reed bars 46, said slots being for the accommodationof the warJ threads or" yarns when the blades are at t ieir eXtreme positions of movement. In those cases where a shuttle is to be used in combination with the traveler, said shuttle may be shot back and forth overthe bar 47' as a trackway. In such cases also any suitable form of shuttle-throw1ng arms48 and 49 may be adopted, and in view ofthe fact that such constructions are well known in the art. 1 W111 not describe the samein detail. For

6 5 me1ttset the. pin556l1havprovided thezbell'a purposes of convenience I have indicated a simple form ofshuttle by the numeral 50.

Referring to the several figures, there will befound a cross shaft 51, located in front of the position occupied by the rock shafts 27 and 28. Said cross shaft 51 is provided with the double threads 52 and 53 which lie in opposite directions. Consequently, a traveler mounted on the shaft will be thrown in the one direction or the other, depending upon which of the threads 52 or 53 is engaged, and the shaft 51 may nevertheless be rotated continuously in the same direction.

*Sli htly behind the shaft 51 is a cross rod 54. 3 traveler 55 is slidably mounted on the shaft 51 and on the cross rod 54, and said traveler is retained against movement out of a given plane by reason of its simultaneous engagement with the shaft 51 and the rod 54. That is to say, the traveler is thus caused to' reciprocate backand forth ina fixed plane of movement. In the front portion of the traveler there is slidingly mounted a pin 56, and a spring 57 tends at all times to draw said pin into engagement with one of the threads of the shaft 51. A lever 58 is pivoted to the traveler at the point 59, the upper end of said lever being connected to thepin '56, and its lower end being provided with a contacting head 60; The shaft 51 turns over in the direction of thearrows shown in Figs. 1 and 4.

The slot 53 extendsover and terminates in a. circular slot 61 at the left hand side of the machine, the slot 52 not being carried into the slot 61 but terminating atthe face thereof. In likemanner the slot 52 runs clear over to the right-hand end of the shaft 51 and terminates in a circular slot, the. slot 53 not being extended into said circular slot, but terminating at the face thereof.

It, therefore, follows that if the traveler be standing at the right-hand side of the machine, namely, the position shown in Figs.

1, 2 and 4,.and the pin 56 be then allowed to drop into the circular slot at the right-hand end of the shaft 51, the slot 52 will take hold of the inner end of the pin 56 and cause the traveler to be thrown or moved to the left-hand side of the machine. g If the pin 56 be withdrawn against the 1 force of the spring 57 as soon as the traveler has reachedthe eXtIBlllGlBft-llfifid limit of movement; then the traveler will stand at said left-hand limit of movement until the pin 56 may again be allowed to drop into the circular slotj61, whereuponit will be engagedj by i the .slotl53. .and caused to. advance back..to athe. .right-handsidei of the. machine;

For thetpurpose of controlling the moves cranks 62 and 63 at the right and left-hand sides of the machine, respectively. These bell cranks have at their upper ends the cam surfaces 64 and 65, respectively, which cam surfaces are so placed and formed that the following actions are secured: Assuming the bell crank 62 to stand with its upper end tilted rearward,that is, toward the shaft 5lwhen the traveler approaches the extreme right-hand limit of movement, the contacting surface 60 will ride up onto the surface 64, thus rocking the lever 58 and withdrawing the pin 56 against the force of the spring 57 If the bell crank 62 be then rocked in the opposite direction,-that is, away from the shaft 51-the pin 56 will be allowed to move into engagement with the thread 52 under the influence of the spring 57.

Assuming the bell crank 63 to be standing with its cam surface 65 in the rearward position,-that is, moved toward the shaft 51- as the traveler approaches the extreme left hand limit of movement, the contacting head 60 will ride up on to the cam surface 65, thus withdrawing the pin 56 against the force of the spring 57 and disengaging the trav eler for the time being from the influence of the slots of the shaft 51.

In the front portion of the traveler there is provided a perforation or opening for the accommodation of the weft thread or yarn 66, which yarn may be taken from a spool or bundle conveniently mounted at any suitable point adjacent to the machine. The forward portion of the traveler carries an extension 67 pivoted to the forward end of the traveler at the point 68. Said extension may be swung or raised upwardly on the pivot 68, but cannot fall below a limit of movement substantially as shown in Fig.4.

The extension 67 is provided with a perforation entering its right-hand side and leaving at its rear end, and the yarn 66, alined along the right side of the face of the traveler, may be fed through said perforation and delivered from the rear end of the traveler inthe manner best shown in Figs.

1 and 4. Manifestly, when the extension 67 a minimum length of amount or-vslack portion*='of' yar'n will be necessaryy and' i consequently "this additional portion will be withdrawn from'the source of. supply flay. bendingcor tilting thei'exten- The whip? roll 1 or Tod 1 22 i is conveniently mounted on mpair of fiarms=69 and 7 0} which extendscupward"from a rock" shaft-7l In Fig. 4tthe rock s'haft and the arms 69 andflo with the whip roll 22 are shown tilted into the extreme forward position,-that is, away from the shaft 51. They may be rocked or tilted so as to carry the bar 22 toward the shaft 51 when desired.

I will now describe briefly the cycle of movements of the various parts, and will then explain more in detail the particular mechanism which I have illustrated for securing the proper relationship in said move ments. In describing these movements I will have reference particularly to Figs. 12 to 19 inclusive, which show the main operative parts in their various consecutive positions. The position shown in Figs. 12 and 12 may be termed the initial position. In it the traveler stands at the lefthand side of the machine, the blades 25 and 26 are spread open, the reeds are separated, the sword arms stand in their rearward position, and the shuttle stands at the lefthand side of the machine.

The first movement consists in carrying the traveler to the right-hand side of the machine, the blades standing in theopen position illustrated in Fig. 12*. This crosswise movement of the traveler will lay in a length of weft thread or yarn, as shown in Fig. 13. The reed dents will then be closed, as shown in Fig. 13. On each of the sword arms 37 and 38 there is a cam block 72 of the general form shown in Fig. 1. The upper face of each of these cam blocks is adapted to lift the extension 67 when the reed dents are brought together, said lifting operations being as shown in Fig. 13. Consequently, the act of closing together the reed dents will raise the extension 67 so as to withdraw the excess portion of weft yarn or twine.

The next operation in the cycle will consist in swinging the sword arms forward so as to pack up the length of weft thus placed. The sword arms will be immediately restored to their forward position.

The next operation will consist in reversing the blades 25 and 26 so as to reverse the positions of the warp twines. This condition is shown in Figs. 14 and 1 1 In those cases where a shuttle of ordinary form is to be used in conjunction with the traveler, said shuttle serving to carry an ordinary thread or yarn back and forth, the shuttle will next be shot from left to right so as to bring the parts into the position shown in 15 and 15 Thereafter, the sword arms with the reed dents closed, will be thrown forward and then back, so as to pack the length of twine thus laid.

Inasmuch as the blades 25' and 26 are crossed at the completion of the movement shown in Figs. 15 and 15, it will be necessary to uncross said blades before the traveler can be sent back to the left-hand side of the machine. Consequently, the next move- This will lay the weft yarn or twine into position, so that upon the next forward movement of the sword arms, this lay will be packed into position. As soon as the traveler has reached the extreme left-hand limit of its movement, the reed dents will be brought together, thus raising the pivoted extension (57 of the'traveler, and thus withdrawing an excess portion of twine oryarn. Thereupon the sword arms will be advanced and immediately retracted, so as to pack the yarn thus laid into position.

The next movement will be to reverse the blades 25 and 26, as shown by Fig. 18 Thereupon the shuttle may be shot back to the left-hand side of the machine into the position shown in Fig. 19, after which the sword arms will be thrown forward and back for the purpose of packing the weft thread thus laid into position. I a

It will be observed that in those positions shown in Figs. 18, 14, and 15 and in Figs. 17 18 and 19, the-reed dents are retained in closed position, so that the extension 67 is retained in raised position by means of the simultaneously raises the weft yarn or twine coming from the traveler, so that the same will be out of the way, and so as to provide sufficient clearance for the shuttle.

Having thus described the various movements to be performed by the different parts, I will now explain the particular construction of mechanism illustrated for performing these movements. These various movements are conveniently efiected by the use of cams mounted on the shaft 73, which shaft performs one complete revolution for a complete cycle of movements of the main operative parts. A lever 74, pivoted at the point 75, carries a roller 7 6 adapted to be engaged by a cam 77 on the shaft 7 3. Said cam has two diametrically opposed dwells 78 and 79 of small radius, and two diametrically opposed dwells 80 and 81 of large radius. These dwells are not necessarily absolutely concentric with the shaft for the reason to be presently explained.

The lower end of the lever 74 is pinned to a link 82, the forward end of which link is pinned to a crank 83 mounted on a shaft 84:, which shaft is journaled in the lower portions of the sword arms. The rods 42 and 13 for the lower set of movable reed dents 46 are provided with sleeves 85 and 86. Cranks 87 and 88 are mounted on the shaft 84:, said cranks being connected to the sleeves 85 and 86 by means of the links 89 and 90.

A spring 91'tends to restore the shaft84 to such a position aswill lower thereed dents d6. Manifestly, with the arrangement thus described, the reed dents will be closed during the travel of theroller 76 on both of the dwells 80 and 81, whereas said reed dents will be opened during the travel of said roller on each of the dwells 78 and 79.

engaging with said cam. The link 97 isalso provided with a forked extension 100, which engages the shaft 73, so that thelink will at all times be properly centered on "said shaft. Manifestly, with this arrangement,

the slack whip roll 22 will stand in the forward position, while the roller 99 rides on "either of the dwells 93 or 94, whereas said either of the dwells 95 and 96.

slack take-up device will stand in the rearward positionfwhile said roller stands on Mounted on the shaft 73 adjacent to each side of the machine isa cam 101 having a long dwell of short radius 102 and a short are for the bell cranks 62, which bell cranks dwell of longer radius 103. 1 These cams 101 carry the rollers 10 1 ridingon their respective cams. With this arrangement it is manifest that as long as one of the rollers 10 1 rides on thedwell, of short radius 102,

the corresponding bell crank 62 will be tilted forward into position to disengage the pin 56 from the shaft 51, and to retain the pin in such disengagement. As soon, however, as'theroller 104 rides up'onto the dwell of longer radius, the correspondingjbell crank 62 will be tilted backward and the pin .56 1

will thus be allowedto engage with the shaft 51.

A roller 118, mounted on said link, engages the cam surfaces 113 and 114. A pair of springs 119 and 120 tend at all times to draw the sword arms rearwardly and thus retain the roller 118 against the cam 112. In order to stop the machine in case of the breakage of the weft yarn or twine, I have illustrated a rod 121 journaled in the frame of the machine and carrying the upstanding the machine, as long as the weft twine or yarn lies inthe normal position, the pin 124:

will be retained in the full line position shown in Fig. 11. In case of breakage of this yarn or twine, however, said pin will be thrown into the dotted line position of Fig. 11, so that when the traveler reaches the extreme right-hand limit' of movement, said pin will strike against the crank arm 122 and thus rock the rod 121 to thereby bring into movement such mechanisms as will bring the machine to rest.

While I have herein shown and described only a single embodiment of the features of my invention, still it will be understood that I do not limit myself to the said embodiment except asI may so limit myself in the claims.
